Application md June 17, 1926. serial No. 116,732..

This invention relates machines. Y

In automatic looms the discharge .of bobbinsl from the loomis controlledby a eeler 5 on the loom which contacts with the bobbin and causes it to be thrown out when the 'bobbin is nearly empty. Y It is necessary, however, to leaveI a small amount ot yarn on Vthe bobbin after the feeler has functioned,

in order to enable the shuttleto complete the pick. For this reasonV the bobbinvis'wound with a bunch ator adjacent thebase of the bobbin to provide this required reserve supply of yarn. n l5 mills to rewind spun yarn for use'. in automatic looms because of the fact that in winding bobbins in the' usual way on the mule. the yarn could not be properly shaped on the bobbin to be suitable for f use in automat-ic looms. In other words, theusual faller control in a spinning mule does not provide for.

building a bunch on the bobbins. This rewindinv of the'bobbins requires theeXpenditure o? time and labor and is a source of Considerable eXpense.- 1

With the above problems in mind, the presi ent inventionfhas for its salient V'objec-tto providean attachment for a spinning mule so constructed and Varranged as to build a bunch on the bobbins; H l, 1

Another object of the invention isto provide a `bunch builder attachment for ia spinning mule, so constructed and arrangedy that the size of the bunch can be controlled, andafter -a bunch of the desired size has been built the attachment will be automatically rendered inoperative and the mule will opern ate in the usual manner.

A'further object of the invention is to provide a bunch builder for aspinning mule so constructed and arranged that exactly the same amount of yarn will be contained inthe bunch on each bobbin.

A still further object of the invention is to provide a builder rail control device so.

This `attachment comprises a supf plemental bunch builder shoe for holding the. builder rail or a portion thereofin position to control the taller leg and vtaller wire'so as to wind a bunch ofl near the base thereof. v y v The supplemental shoe is placed in juxta-V position to or `side by vside with vrelation to the back builder shoe, and when the supplemental shoe is operating the' control ofthe back portion of the builder rail isi-taken away from the back shoeV and exercised by the supplementalshoe.- Ther supplemental shoe is placed inoperative position by Athe rotation of the re-set mechanism for,k the yso yarn onthelbobbins 'i builder Yshoes andl is retained in operative f positionV for a predetermined number" of draws. The shoe-control cam plate-,which moves the shoepto operative position and supports the. supplemental shoe in operative. position can be so adjusted that a Vbunch of` the desired size can be built, and this ca ma way that after a predetermined number of f plate is fed at each draw ofthe loom in Such draws the plate will be lowered thereby, permitting the supplemental shoe to drop out of operative position. Y

Further Adetails of the invention will appear from the following specification.

The spinning mule disclosed herein is of the usual construction, and therefore, the details of construction and the details of the operation of the various parts of the mule need not be described at length.

Briefly stated, the mule comprises a builder rail which is made up ofa back section and a front section 11. The back section 10 has a roller 12 secured thereto, the front section 11 has a roller 13 secured thereto, and a third roller 14 is disposed at the junction of the sections as shown in Fig. 2. The central portion of the shoe is guided vertically by a U-shaped bracket 15 in which is positioned a stud 16 on the `outer end of which the roller 14 is mounted.

lThe builder rail is normally supported on three builder-shoes, a back shoe 20, a center shoe 21, and a front shoe 22, and these shoes are slidably mounted on suitable bases and are connected to and controlled by a builder rod of the usual construction. The

builder-rod is fed longitudinally by means of a quadrant lever' 26 which is engaged by afroller 27. carried `by an arm 28 secured to the carriage. It will be evident that each time thecarriage moves to the 'front of the machine the quadrant lever 26 will be tilted on its axis 29. As in the usual construction the quadrant lever feeds a pawl 30, which in turn rotates a ratchet wheel 31 carried by a shaft 32. This shaft has formed thereon a screw 33 which engages a threaded bracket 34 secured to the builder rod 25. A crank handle 36 is secured to the outer end of the shaft or spindle 32 for manually resetting the shoes after the winding of the bobbins has been completed.

The builder rail performs its usual function of controlling the winding of the yarn on the bobbins. The rail is engaged by a roller 40 carried by a builder arm 41 slidably mounted on the builder carriage 42, and the builder arm 41 also has a roller or stud'43 adapted to be engaged by a notch 44 in the faller leg 45, when the mule is in position to wind the yarn. The faller leg 45 lis connected in the usual manner to the faller rod 46 on which are mounted the faller or guiding fingers 47 having faller wires 48 secured thereto. 'These fingers control the course of the yarn being wound on the bobbins and operate in the usual well-known raised, lowering the faller rod and the faller guiding fingers 47.

`.Bu/)wh builder attachment.

The present invention as above explained, h'as f'or its 'object-to provide means for taking the control of the builder rail away from the back builder shoe 20 vand for so positioning the railas to cause `the faller leg and faller wires to build a bunch adjacent the base of the bobbins. y i

The attachment Vis vmounted on a baseplate 60 having a pair of cam surfaces 61 and 62 `extending upwardly Y therefrom. These surfaces are adapted to co-act with cam surfaces 63 and 64 formed on the su 3- plemental shoe supporting member 65. T e supplemental shoe 66 is slidably mounted by a pin and slot connection 67 on the back shoe 20, and rests, as shown in Fig. 5, on the upper surface `68 of *the shoe-'supporting member 65. In Fig. I5 the'supporting member is shown in operative position, or in elevated position on l:the lcam surfaces 61 and 62, and it will be evident from the showing in this figure, that the Acontrol of the back roller 12 and the back portion of the builder rail is exercised by the supplemental shoe 66 and has been taken away from the back shoe 20. The supplemental shoe support-ingmember is moved manually to operative position as shown in Fig. 5, but is 'automatically returned to ino erative position after a predeterminednum r of draws.

The shoe is moved to operative Vposition by means ofa pawl 70 which is pivoted to an adjustable bracket 71 secured to the builderrod 25. The front end of the pawl 70 is adapted to engage a'pin 72 carried by the front end of the supplemental shoe support 65. The pawl 70, as'shown in Figi, hasa lug'731extending upwardly therefrom, and a pin 74 is carried by the lug and is adapted to engage an inclined lug 75 which is formed on the base 60 whenthe plate65 is moved to operative position as shown in Figf.

It will be understood that the builder shoes must Vbereset after Vone set of bobbins has been wound, and as above explained, this is accomplished by manually rotating the crank handle 36 and thus moving the builder rod longitudinally in position to reset the builder shoes. As this rod ismoved longitudinally it willalso reset tliesupplelun llo

'mental buildershoe 66 since the: `pawl 70will 4draw the supplemental builder shoe support and raise the support on the cam surfaces 61 and. :62.

As above stated afterthe predetermined number of draws, the supplemental builder shoe" is 'put out of commission. This is accomplished by a pawl 8O pivotally mounted at 81 on a bracket 82 secured to and carried by the back-od rod 51. The pawl 80 is adapted to engage rack teeth 83 of a rack 84 adjustably secured, as shown at 85, to the upper surface of the support 65. The pawl 80 has la pin 86 extendinglaterally therefrom and Aengaging' a cam surface 87 and the pin is adapted to rinde yback and fourth on this cam surface when the supple- 'mental rail is in inoperative position as shown in Fig. 1.

Vhen the rail is in operative position, however, as shown in Fig. 5, the pawl and cam are so relatively positioned that the pawl will feed the rack and support 65 a distance corresponding to one rack tooth tion to start the operation of the machine. Assuming that a bunch is vto be built on the bobbins, the'movement of the builder. rodV will cause the pawl to elevate the support tion it will be seen that the control of the back end of the builder rail is taken away from the builder shoe, and is exercised by the suppplemental builder shoe 66. The supplemental builder shoe will remain in commission until the support 65 `is fed step by step by the pawl by drawer, and after a predetermined number of draws the sup port 65 will reach a position in which the cams 61 and 62 enter the recesses formed by the cams 63 and 64, thus lowering the supplemental builder rail to inoperative position as shown in Fig. 1.

From the foregoing specification it will be seen that a simple and practical attachment has been provided for spinning mules, whereby a bunch having the desired number of turns or windings can be built on the bobbins.

Furthermore, it will be evident that all of the bunches on the bobbins will be uniform in size and shape by reason of the bunch builder attachment. The necessityV for' rewinding the bobbins which have been wound` on spinning mules. is obviated, thus effecting a material saving in time, labor andexpense.`

Although one specific embodiment of the invention has been particularly shown'and described, it will be evident that the invention Vis capable of modication, and that changes in the construction and in the arrangement of the co-operating parts may `be made without departing from the spirit and scope of the invention as expressed in the following claims. y
